This invention relates to bats for use in upholstery and the like. i

In the upholstering of seats and cushions and particularly of chair andautomobile seats and backs, it is customary ,to put overv the springsone or more layers orbats, and the upholstery covering is then placedover the bats. Cotton bats have been customarily 7 used heretofore forthis purpose, but they. 10 are not particlarly elastic or strong intensile strength, and frequently it has been necessary to stitch thecotton bat to burlap or other fabric which is placed over the coils orsprings in order to prevent the punching of holes in the cotton bats bythe coils or springs. If the cotton bat were reinforced with paper orthe like, in order to give it tensile strength,

it would be inelastic and could not accommodate itself to undulations inthe surface covor creases which would be objectionable.

An objectof the invention is to provide an improved bat of this type,which will have maximum strength; which will be somewhat elastic; which,will accommodate itself to undulations in a surface or object coveredwithout the formation of ribs or ridges; which may be used without aburlap or other fabric back; which may be easily made in various sizes,and which will be relatively simple and inexpensive.

.A further object of the invention is to provide an improved method ofmaking'a bat which will accomplish the above objects.

" Various other objects and advantages will be apparent from thefollowing description of an embodiment of the invention, and the novelfeatures will be particularly pointed out hereinafter in connection withthe appended claims. v

In the accompanying drawing Fig.,1 is a perspective illustrating one ofthe steps in the manufacture of one of the improvedbats;

Fig. 2is a plan of a portion of one of the component bats;

Fig. 3 is a transverse, sectional elevation of the same;

5 Fig. 4 is a plan of a portion of an improved ered' thereby withoutformation of wrinkles bat during an intermediate step in itsmanufacture; e

vFig". 5 is a transverse section of thesame;

Fig. 6 is a perspective of a portion of the same, partially folded toindicate the manner ,55 in which it is folded ;and I Fig. 7 is a similarperspective illustrating the improved bat as completely folded.

In accordance with this invention, and referring particularly to thedrawing, a cot ton or other fibrous bat lis first formed in a perfectlyfiat condition, and another bat 2 of tough fibrous material, such asjute, is similarly formed and deposited upon the cotton bat 1, The twosuperposed bats are then preferably passed and compressed betweenrollers 3, which cause the fibers in the abutting faces of the two batsto interweave with one another to some extent, so that they will Vadhere-toone another, and therefore be more .7 easily handled insuccessive operations.

The side edge or marginal portions of the. combined bat are then foldedover upon the same face of the bat, that is upon the jute or toughfibrous'bat, as shown in Fig. 6, the 7 folded edge portions overlappingwith one] another somewhat as will be observed from Fig. .6. The batwhen completely folded is shown in Fig. 7, and the folded bat is preferably then further compressed'or rolled by pressure applied to oppositefaces thereof, which further interknits or interlocks the fi bers orabutting layers in such a manner that they will adhere while the bat isbeing handledfor upholstering purposes.

The hat of loose, tough fibers which forms the core or lining of thecombined bat, gives the finished bat great tensile strength, so that itmay be used directly without theuse of a burlap backing, and issufficiently elastic to V accommodate its'elfto all'undulations of thesurface to 'be covered thereby. The finished bat has great strength toresist the punching of holes therein by any projections on the surfacebeing covered, and the cotton outer surface gives the bat a goodappearance which will not show through the usual coverings or present anunsightly appearance if the cow. ering is thin. p

The cotton or outer bat is preferably somewhat Wider than the innerbatof jute or the like having the long, toughfibers, and the marginaledge strips of the cotton bat preferably taper in thickness outwardly,that is, they are made thinner towards the extreme side edges,as showninliigs. 3 and 4, and then when the bat is folded as shown in Figs.

\ 6 and ?.the ta ere d edges which overla will P U P not form ridgesinthe finished bat, and the finished bat will be of substantiallyuniform thickness across its entire width.

Incasket work, sue-ha combined bat of cotton with a jute core is cheaperthan an all cotton bat, and since the cotton forms the exterior coveringof the combinedbat, it pre-' sents an attractive, white appearance,which i will not show under silkli'nings.

The finished bats may be made entirely by machinery, of any desired-widths,:and folded and rolledjin long strips or; rolls. Conse quently',the cost of manufactureis relatively low and quantity produetionisfeasible. c The projecting side edges of the cotton bat, as shown inFigs. 4: and 5, cover the jute or other care after the combined bat hasbeen foldedyandthe finished bat, due to interlocking of the overlappingcotton, is in re'ality a contlnuous tubular cottonbat, completelyenclosing 'athin: fiat, elastic andstrong core of" tough fibersrThis'combined tubular bat may also'be turned" or further foldedanynumber of times,jand-the m'oreit is turned, the stronger itbeclonies, I 1 V Each component bat n'ia'y' be separately formed in anysuitable or usual manner,is uch' "as by first card ng or garnetting thefibers,
